bought the polarizing filter from K&F and I'm absolutely thrilled. This isn't my first filter from K&F, and I have to say, the company's quality never ceases to impress me. The filter's workmanship is first-class. It feels robust and high-quality, which isn't always a given in this price range. K&F has once again succeeded in delivering a product that's not only functional but also aesthetically pleasing. The packaging is, as always with K&F, very good. The filter arrives safely packaged to ensure no damage occurs during transport. Everything is very neatly and professionally packaged, which I really appreciate. A particular highlight is the magnetic attachment of the polarizing filter to the lens. This is ideal for quickly taking a picture without a filter, without having to fiddle around with it for a long time. Simply remove and reattach it – brilliant! The quality of the filter is incredibly good. Once mounted, if you turn it counterclockwise, you can immediately see the change. In this case, the filter minimizes reflections, which makes a huge difference, especially on water or glass surfaces. The colors become more vibrant and the images clearer. I love this company and its products. K&F has never disappointed me. Today, it's even on sale for just €20 on Prime Day—I just had to jump at the chance! Bottom line: The K&F polarizing filter is an absolute must-have for every photographer. It offers excellent quality, is easy to use, and the magnetic attachment is a real plus. I definitely recommend it!
